Inside out Solar Dehydrator

I'm about to build myself a solar collector outside, cabinet inside dehydrator. The cabinet will be in the southwest corner of my to be canning / processing room. Being in the corner, two of the walls are already built.

Typically the false wall chimney is opposite the collector intake. My question is, can the false wall be against the west wall 90 degrees to the collector intake.

Another question, Has anyone used a plenum to help distribute the income warm air?

I'll start here. What say you?
